Egypt Coptic Church Bombing

From CBC News:

Dozens of grieving Christians attended mass at the Saints Church in Egypt's Mediterranean port city of Alexandria on Sunday, the day after 21 worshippers were killed there in an apparent suicide bombing.

The service was marked by the grief and anger felt by a congregation devastated by the attack, which took place outside the church's door about 30 minutes into the new year as churchgoers were leaving.

Hans Wendt alerted me to the tragedy, suggesting that it would have powerful repercussions. I set a GCP event for three hours beginning at midnight, local time, which was about 30 mins before the bombing.

The result is Chisquare 10706.886 on 10800 df, for p = 0.736 and Z = -0.631

It is important to keep in mind that we have only a tiny statistical effect, so that it is always hard to distinguish signal from noise. This means that every "success" might be largely driven by chance, and every "null" might include a real signal overwhelmed by noise. In the long run, a real effect can be identified only by patiently accumulating replications of similar analyses.
